Hi Joe As far as I know, PLMTUD provides an extension to PMTUD and does not deprecates the legacy. ICMP can be one of the potential upper-layer protocols which can be used for PLMTUD as well.
Even though PLMTUD is ICMP agnostic, ICMP PTB¹s can be leveraged in determining probe success/failures, and also detecting ICMP black hole to further refine the probe. Ensuring that icmp PTB generated from the underlay is percolated to end point device should only aid PLMTUD and reduce the scope of icmp black-holing. Thanks Saumya.
